Django 1.7 introduced Migrations so now you don't even need to install extra package to manage your migrations.
To rename your model you need to create empty migration first:
$ manage.py makemigrations <app_name> --empty
Then you need to edit your migration's code like this:
from django.db import models, migrations
class Migration(migrations.Migration):
dependencies = [
('yourapp', 'XXXX_your_previous_migration'),
]
operations = [
migrations.RenameField(
model_name='Foo',
old_name='name',
new_name='full_name'
),
migrations.RenameField(
model_name='Foo',
old_name='rel',
new_name='odd_relation'
),
]
And after that you need to run:
$ manage.py migrate <app_name>
